समांतर श्रेणी \(13,18,23,28,\ldots\) का (20)वाँ पद क्या है?
What is the (20)th term of the arithmetic progression \(13,18,23,28,\ldots\)?
Explanation opens after your attempt
B. (108)
Concept
Here (a=13) and (d=5), so (a_{20}=13+19(5)=108). Use (a_n=a+(n-1)d) even for larger terms.
Why this answer is correct
The correct answer is B. (108). Here (a=13) and (d=5), so (a_{20}=13+19(5)=108). Use (a_n=a+(n-1)d) even for larger terms.
Exam Tip
यहाँ (a=13) और (d=5), इसलिए (a_{20}=13+19(5)=108)। बड़े पद के लिए भी (a_n=a+(n-1)d) लगाएं।
